Prospex Alpinist: 1959 Sport Watch Reinterpretation Built for the explorer in you. The Seiko Prospex Alpinist channels six decades of sports watch mastery into a modern reimagining of the brand's first sport watch. Smaller case, vintage soul—the gradated green dial, LumiBrite hands, and curved anti-reflective sapphire crystal strike the balance between heritage and contemporary wrist presence. Engineered for real adventure. The 24-jewel automatic movement delivers 70 hours of power reserve, beating at 21,600 vibrations per hour. Manual or automatic winding keeps you going. Stainless steel construction, screwdown crown, see-through caseback, and secure tri-fold clasp ensure durability where it counts. Water resistant to 200M, ready for whatever comes next. A watch that honors the past while pushing forward—proof that the best tools never go out of style.
